vrain new and useful Improvements in Thread-Fastening Machines; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same. v

The present invention. relates to thread handling machines and moreparticularly to improvements in machines of'this type employed forsecuring the upper and insole lip of a lasted shoe.

The objectof the present invention is to provide mechanism fordisplacing the toe binding wire to insure the proper location of the toethread about the toe of the lasted shoe and at one side of the Wire, andpermit the subsequent removal of the wire without interference with thetoe thread.

With this object in view the several features of the invention consistin certain novel features of construction, combinations and arrangementsof parts hereinafter described and claimed, the advantages of which willbe obvious to those skilled in the art from the following'description;

In the accompanying drawings illustrating the preferred formof theinvention, Figure 1 represents a side elevation of a thread handlingmachine embodying the present invention; Fig. 2 is-a front elevation ofthe machine shown in Fig.1; Fig. 3 is a front elevation of the head .ofthe machine shown in Fig. 1; Fig. 4 is a side elevation of the headshown in Fig.' 3; Fig. 5 is a. detail illustrating a plan view partly insection of the constructionfor supporting and actuating the channelguide and thread finger; Fig. 6 isa, detail illustrating a plan view ofthe toe wire lifter and back gage in the position which they occupy whenpassing about the toe of a shoe; and Fig. 7 is a detail illustrating aview of the toe wire lifter in operative relation to the shoe showingthe relative vertical positions of the The illustrated. embodiment ofthe presentinvention'is shown in connection-with the thread handlingmachine'disclosed .in

the patent. to La Chapelle No. 1,185,108, dated May 30, 1916. Thismachine is arranged to insert a plurality of individual unconnectedthread fasteners through the upper and insole lip of a lasted shoe toretain the shoe in its lasted condition and permit the removal of thelasting tacks prior to the welting operation. The thread fasteningmachine comprises a curved neetile 1 operated from a needle actuatingle- 1 ver 2 through suitable connections to pass two separated loops ofthread through the work, mechanism being provided for imparting arectilinearfeeding movement to the needle between the passage of eachloop of thread through the work comprising a peripheral cam indicated at5 and connected to a movable head 6 through the usual cam roll. The Workis held during the formation and insertion of the. thread operating backgage 8 engaging respectively in the channel of the shoe and with theout- The channel guide is normally held stationary during the opera tionof the machine and the back gage is moved toward the channel guide inthe usual manner to engage with the shoe and is then looked in theadvanced position. to clamp the shoe firmly. The first loop of thread isengaged by a thread finger 9 supported upon a head 10 to which arectilinear movement is imparted at predetermined intervals to pass thefirst loop of thread through the second. During the normal operation ofthe machine the supply thread is severed at the completion of the threadfastening by a thread cutting knife 12 pivoted' upon the'back gage andoperating to shear the thread against the slot. in the back gage. Thethread cutting knife is non mallyoperated through an actuating memberindicated at.13 which may v:be moved into an inoperative positiontoprevent the cutting'of the thread when it is desired to bind in thetoe of the shoe with a thread we passed about the toe and connected atits opposite ends by thread fasteners This mechanism is clearly shownand described .1n the patent above referred to and in consequence hasbeen only briefly described The toe of the lasted shoe is preferablysecured by a thread which passes about the toe and is secured at itsopposite'ends'by" thread fasteners located at oppos1te sides ofthe toeof the shoe; This-toe threadsecurely binds the toe, of theshoe in placeand per-v mits'the removal of the usual toe wire and anchor tacks whichhold opposite ends of the wire. It is desirable to provide mechanism forinsuring that the toe thread shall be locategl' 'enti1'ely,,-at onesideof the toe wire-in order to permit the convenient removal of the toewire and anchor'ta'cks atthecom' pletion of the thread fasteningoperation Without liability of removing the toe thread therewith.T'o"this"end' the present invention; contemplates the provision of'a wre lift mgme'niherwhlch lsmoved nto an operati v'e position when passingthethre'ad about tlie'toe of tli'e shoe andis arranged t6 lift the wire,permitting the to e thread'to he, located at one side of the wire. Thewire lift ing; member "is employedin connection with theba ck gage toform two points of "support which 'servefasguides' for theshoe' when 1turningji'abontthe, toe. Thewirelifting.

member comprises: roll havi g n up,

wa'rdlyff inclined" peripheral face which serves tofengagei'beneath andli ft' the toe wire? when the shoe is essed; against' the roll'fasshowncl'early in' the drawings; In the "illiistr'ated embodiment of theinvention a roll 20 is supported upon the outer end of a curved 22'adjustably. secured toa slide23. throughthe'usual bolt and slot connecfti ons'findicated"at 24. The slide 23 is supporfted in an. inclinedhead 26' secured tothe machine frame and is arranged to movetov'v'ardfand from the'shoe, as shown clearly in the drawings; a Thewire liftingQmember is preferablyikmoved into an operative positionafter the machine has stopped and while assingthe thread about the toeof the shoe.

o this end the slide 23 is actuated through mechanismfunderth'e controlof'the operator; 'The slide is connectedwith an actuat: ing. rod27'throughan: arm 28 secured to. a

advancing, the ;slide. 23through the link 38 and moving the roll intothe position shown sub'stantiallyin Fig. 6. In this position theroll-and back gage form cooperating work supporting: and guidingmembersagainst which--theshoe;is firmlypressed when passing a thread about; thetoe,- As shown clearly in Figs. 6 and 7 of the drawings the positi'onof'theroll with relation to the shoe causes the roll to engage beneathand gradual-ly..-lift'the toe wire as the roll progresses about the toeof the shoe. In order to aid in thepositi'oning"of the toe thread andinsure that the toe threadshall lie closely against the upper, the roll20is provided with a t pered'under face 42 which serves to sepa ratetheme wire'indica'ted at i and the toe thread indicatedat45 in Fig. 7ofthe drawing's', but ress s upon the toe thread, causinf itf tdlieclosely-against the upper and su stanti'al ly' inthe groove in the upperpreviously. occupied by the toe wire.

In'this type of machine the work is firmly clamped 'betweenfihe backgage and channel guidedurin'g the formation and insertion of thethreadfasteningand at the completiolfOfth thre ad fasteningithe back ga e isretifact'edl to";permitth'e convenient refmovatofthe shoe. Inorder topermit the convenient turning of the shbewhen thread v ing. the toe,however, it isdesirable to increase. thefeifectivef; space in which theshoe ma be turned. To this end, mechanism is provided for impartinganoutward movement of separation'tothe channel guide and threat-stin er."In thesimplest andinost eflioient form ofthe invention which has yetbeendevisedthe channel guide and thread finger areconnected With-themechanism for operating the wire liftingroll' and are auto.- maticallyImovedoutward upon a movement of the roll into operative position." Tothis end the channel guide (is secured to'the lower endiof anjarm47having a forked upper end 48 pivoted upon a guide rod 50, asshownclearly in Fig.;.5 of the drawings. The arm 47 is-provided with asecond :arm 51 extending. upwardly'therefrom and "connec tedwith an arm52 which is connected 7 at tsopposite end to the peratingrod 27. p Thearms 28 and52together form a toggle leve-r whichis broken'by the rod 27to simultaneonslyactuate the. wire lifting; roll and channel guide'and'serves -to lock the channel guide inoperative position when the 1wire. liftlng roll 1SdI1QPt-3fll2ttiYe. Tothis end, as shown clea'rly in-F1g L- of; the drawings,

the inner; ends; *of fthe arm s: 28 and 52 are provided respectively'withdependingnlugs 53 and '54Lwhiehengagewith onesanothe'r.

he the w -ar the le l ve a moved beyond an' aimed-position, positivelyin either direction. The.--threa,d finger 9 is lockingthe channelgmdeagainst movement supportedfupon parallel 'guidegrods 60. and

.61." The, threadlfinger is-secured to the lower end of an inclined arm62 pivotally supported at its upper end upon the guide rod 61 and forkedto embrace the lower portion of the head 10, as shown clearly in Figs. 3and 5 of the drawings. The arm 62 is operatively connected with theslide 23 through a rearwardly extending arm 65 projecting from the upperend of the arm 62 and having a slot 66 formed in its lower end whichreceives a slide block 67 pivoted upon an upstanding lug 68 formed uponthe slide 23, as shown clearly in Figs. 4 and 5. With this constructionit will be noted that the advancing movement ofthe slide 23 serves toswing the arm 62 and. thread finger outwardly with the channel guide.The thread finger is returned to its initial position by a spring 7 0connecting the arm 65 with the frame of the machine. With thisconstruction the rectilinear movement of the thread finger during theformation of the thread fastener merely causes a relative lateralmovement of the arm 65 and slide block 67 received therein withoutbreaking the operative connection.

The'preferred mode of operation of the improved construction is asfollows: A thread fastener is inserted at one side of the toe inproximity to one of the anchor tacks, the thread cutting mechanismhaving been previously rendered inoperative to prevent the severing ofthe thread. At the completion of the thread fastening the shoe isreleased by the rearward movement of the back gage and the operator thenactuates the lever 35, moving the toe wire lifting memberinto operativeposition, and the channel guide and finger outwardly to permit theturning of the shoe. The shoe is then pressed firmly against the backgage 8 and roll 20 and turned upon these two members to lay the threadagainst the upper. As the turning of the shoe about the toe progressesthe roll 20 engaging beneath the toe wire lifts the wire and causes thetoe thread to lie closely to the upper in substantially the positionpreviously occupied by the wire. When the thread has been completelypassed about the toe the actuating lever 35 is re leased and thestarting treadle of the machine depressed to clamp'the shoe in positionand insert a second thread fastener which serves to secure the toethread in place.

While it is preferred to employ the specific construction andarrangement of parts shownand described, it will be understood that thisconstruction and arran ement is not essential except so far as speci edin the claims, and may be changed or modified without departing from thebroader features of the invention.
